My team is wondering if the GPU performance for AI inference will be affected by simultaneously encoding video on the Jetson Orin? We found the following architecture diagram which shows that the data flows directly from the CSI x4 input to the Video Ingest and then to the NV Encoder.
It seems that the GPU performance will not be degraded by simultaneously encoding four video streams because the encoder is on separate hardware, but we wanted to verify this.
Also, we are using SDI camera data, and we are looking at bridge hardware to bring the SDI stream in through PCIe or with CSI x4. Is the CSI x4 much faster than bringing in camera data from the PCIe? Will the PCIe input achieve the same encoding speed as with CSI x4?
Any help is much appreciated.
